23 Claims.

This invention relates to gauging mechanism, especially to means for indicating dilerent diameters of such cylindrical 'structures as rubber sheathed conduits, and more particularly to the determination and indication of such differences in diameter as are encountered in the fabrication of rubber sheathed conduits in a machine of the type known to the art as a tuben In my copending application for United States Letters Patent Serial No. 146,845, led June '7, 1937, disclosure is made of means to apply a regulated amount of rubber to a conduit, forming thereon a sheath of desired thickness and the means for regulating the thickness of such a sheath are spaced circumferentially around the head from which the sheathing material is extended as the conduit is advanced through the extruding orifice.

In order that the regulating means maybe adjusted accurately, it is desirable to ascertain the actual thickness of the sheath as it is being formed and to provide an indication of any disconformity from the proper tubular contour of such a sheath. y So far as known to applicant no diametersensing means of conventional character are suitable for the above-stated purpose, as existing devices of the nature of micrometers, calipers or other diameter-sensing mechanisms are designed particularly for application at opposite ends of a diameter of a rigid cylindrical structure, such as a piston, a calendar roll or a rod, in which the indication, however sensitive, is merely that of a variation in diameter and sometimes only of a variation in radius at a single diameter, and these aiford but little indication of plural disconformities with accurate location of their position, unless the roll, piston, etc., be rotatable.

Inasmuch as an extruded tube is ordinarily not rotated during extrusion, the devices above mentioned are not available, and under such conditions it is the primary object of the present invention to provide a diameter-measuring which While not confined to diametrical measurements of resilient tubular structures as they are being extruded, will nevertheless be especially useful in accomplishing the measurements thereof for which no mechanism exists at present.

In pursuance of the above general object, a more particular object is to provide a diameter indicator of the class described, with a plurality of abutments adapted to be set in fixed adjusted position for contact at spaced regions with the periphery of the article whose circumference is to be tested; a plurality of movable adjustments 55 adapted to be lpresented respectively in yielding con'tact with said periphery atspaced regions oppositely disposed relatively to the fixed abutments, a connecting means for each of said movable abutments and each adapted t0 be moved independently by movement of its abutment and an indicator to furnish indications of Ythe movements of said connections.

A further object is to provide means by kwhich the ,movementsof said connecting means are integrated in course of transmission to the indicating means, whereby the la/tter is adapted to furnish an indication of the resultant of the com bined movements ot said movable vabutments, thereby indicating a mean of variation in the dimensio-ns of said'cylindrical body at -angularly displaced radii.

` Still another object ofthe invention is to provide an -auxiliary indicator and connections therefrom to the vsystem of abutments whereby an indication will be furnished of a bodily displacement of the longitudinal axis of the cylindrical body being measured, caused by an increase in length of one or more radii extending toward one or more of the xed abutments; and as an ancillaryobject, the provision of means to coordinate the last-named indication Withthe rstnamed indications by index pointers disposed in conveniently observable juxtaposition` uponl a common dial.

Another object is to provide for saidv abutments a common supporting standard constituting a portable unitary structure which can be moved readily to a selected station in convenient proximity to the extrusion head of a tuber, and ancho-red there in position for advancement of the extruded sheathed conduit through the system .of abutments.

Other objects and features of the invention will appear as the description of the particular physical embodiment selected to illustrate the invention progresses.

Fig. 8 is a plan view, partly in section on the line 8-8 of Fig. 7;

Fig. 9 is a iront elevation of a modified construction of instrument, embodying the inven-` tion; and

Fig. 10 is a section on the line Ill- I0 ofFig. 9. Referring t0 the drawings and iirst to Figs. 1 to 8 inclusive, lthe part designated generally by the reference character S is a standard by which the several elements 'of the measuring device are supported portably. The standard includes telescopically assembled members I I, I2 and I3. The

member II is iixedly mounted on a carriage I1 which may be supportedby casters I8, when it may be rolled from place to place; These casters, however, are adapted to be raised from the floor 'and thecarriage held ina xed position by handscrews I9 mounted inthe carriage and adapted, whenscrewed downwardly, to contact the floor and raise the casters therefrom. When the instrument'has been rolled to a desired position on the casters, the casters are lifted from the 'floor' and the carriage held in the position in which the sheathed conduit C i's in alignment "with,Y and adapted to be advanced from, the system of'abutments designatedgenerally byl the reference character A, the instrument being thus readily vrolled to a desiredk position Iand thence rmjlyestablished thereon. Jam-nuts I9` serve i.o'prevent' casual displacement of the screws I9. 'The' member I2 is tubular having a central ',"penin'g I6 splined within" ythe .member II by ,man'sloffa key I6', the tube I2 being thus capable of Asliding longitudinally, but not turning, `with.`rel'ation to the member II. y,

Theabutments may be adjustedfvertically by, means `of a .hand wheel 20 having a lhub.2I in lscrew-threaded 'engagement with the tube I2` and l?)caring upon thev top end' of the member II, the

'supporting standardl I2 and the abutment system carried therebyV being adjusted as to Yheight by other.` l

"Surrounding, and in screw-threaded engageamentat 22 with the member I2 is a sleeve I3 having the slit sleeve I4 at its upper end, such Jslit sleeve having a tendency to springaway from Hthe'tube I2 so that' it may have movement with relationY thereto, but the sides of the sleeve may 'jbedrawn together by a screw I5 to cause vthe Vsiem/Je" 14j to' grip the tube l2 to damp k,it inf position.

`Thesleeve I3 is provided with a hand-wheel yfturnjedior"lield stationary' with relationto the tubular standard I2. ",The' vsleeve I4 is provided Awith a supporting bracket 24. i A the standard, and slidablyY mounted thereon, is a split sleeve 25 r,which Ir1a.'y"'ll:re' drawnitogether to clamp `it' in flxed'position' lupon the standard I2, orY maybe loosened to permit relative movement with rela'- tion to the standard I2, by means of a screw 26. This sleeve 25 carries the movable abutments M and M and the dial D with index scales I' and I. The sleeve 25 and its carried parts can be adjusted vertically by means of the hand wheel 29, as before referred to, but is provided with a nicer or vernier adjustment as4 follows:

The top of thetubular standard I2 is provided with a lateral flange 9|] within which is rotatably mounted the member 9I which, at its lower end` 92, is in screw-threaded engagement with the walls of a bore 93 in the sleeve 25. The screw member 9 Ihas at its upper end the knurled linger wheel 94 for turning it. The screw member 9I is provided with a circumferential groove 95 within which nt the edges of a plate 96, such edges being about the recess 91 in the plate, and this plate 96 is lixedly secured to the end of the tubular standard I2 by means of a screw 98 passing through the plate and in s crew-threaded engagement with the interior of the member- I2.

It will now be apparent that by turning the screw member 9I'in one direction or the other that the sleeve 25 will be moved (when the screw 2'6 is loosened) `upwardly or downwardly according to the direction of turning of the screw member SI, and that the movement of the sleeve v25 will be very gradual so that a very line Vernier adjustment is secured. When adjusted to its desired position, the sleeve 25 may be secured in such position by tightening the screw 26.

In order to prevent the adjustment thus effected from being accidentally disarranged or tampered with, a means for sealing the adjust-Y ment is'provided by means of a metal strip 99 secured in a Xed and not' readily removable manner to the tubular standard I2 by means of a rivet |00 or a suitably locked screw. This strip 99 `extends into a recess or slot IUI in the sleeve 25, the strip sliding in the slot as the sleeve 25 is adjusted as described. When the desired adj'jusltment has been reached, a sealing metal, such as lead, |02 is poured through the hole in the Strip 99 and into receSsI03 in the sleeve 25, a head being formed by the lead outside of the lstrip ,asy shown. The lead having hardened, it vwill be seen that-the'sleeve 25 will be sealed against relative `movement on the tubular standard I2, and thatsuch movement can only be again effected by breaking the seal (removing V'the' lead) whereby the sleeve 25 again becomes movable with relation to the tube I2. The collar f 2'I is fixed to the sleeve I2 by a dowel'pin 28.

'The sleeve I4 has a bracket 24 carrying a frame `33 from ,which extends the rod 32 fitted at its outer end with a co-axially adjustable iixture 3I from which'extend's upwardly a fork 30, the, arms czaf9 which arelprovided with anti-friction rollers guides for the sheathed conduit or hose C as it `advances from the'eXtrusion orice ofthe tuber (not shown).- `Jamnuts 28 hold the rod 32 in its adjusted position.

" While the fork'rollers 29 just vdescribe serve adequately as guides, it should be understood v 'that the -vsheathed conduit C is of considerable weight, more or less unwieldy, and at this region of its length, having just been extruded, has not ,attained its final condition of solidity, Vso that ifor all of the above reasons it iseminently desirable that its support during the measuring oply' aligned.

The" invention provides for this. purposeabutments A and A adapted to afford a rolling sup- The. rollers as indicated in Fig. l serve as ljusted in the manner facades-i port to the advancing sheathed conduit, l'the rolls thus provided being carried by studs extendingdivergently from brackets 36 on heads 31.slidingly adjustable on hollow posts 38 set on,-and preferably formed integrally with, the frame 33. The posts 38 include bearings 39 for threaded adjusting screw shafts 40 and 4| which-are connected together by bevel gears 42, 43 and one of the shafts, as-40, may-desirably'have asuit- 'able means, as the knurled head 44, by which it may be readily turned for purposes of adjustment, such rotation resulting in a complemental rotation of 4|.

The screw shafts are thus screwed through blocks as 45 formed as parts of the heads 31, each block having a part-45 secured thereto by screws 41,1and a face plate 48 secured to the head 31 `by the screws 41, serves as an index means to indicate the basic diameter of C.V

When the abutments A and A" have been adjust described according to the diameter of the sheath to be tested, they preferably remain in this basic position for all conduits of the same diameter or similar diameter within a given range, and it may be observed thatpreferably the rolls A and A will occupy respectively positions of adjustment tangent to the conduit sheath C at a point diametricallyopposite to the point of tangency occupied by the correspondingly opposed roll M or M, as the case may be, of the movable abutments which will now be described.

Each of the rolls as M (see Fig. 4) is journaled in a pair of brackets 5| carried by a plate 50 mounted pivotally at 49 on a base 52 secured to an apron l53 which is provided on the sleeve 25 vshown in Fig. 5, and constitutes the main support for the structure included in the head I-I. As shown in Fig. 4 the angular position of the plates can be controlled by the Calibrating screws 54, which serve as means to set the rolls M and M" respectively to the correct initial positions of tangency against the conduit sheath C being tested, and at the same time sets the pointers P and P" at their respective zero points on the index scales I and I". n

The journal posts 55 of each roll, as M', are mountedin arms of a yoke, as Y and Y, from each of which a connecting rod, as 5S and 51, runs to a shackle, as 59, (see Fig. 4), which embraces the Vflanges of a trough-shaped lever, as L', L", each of these levers being pivoted at 6B to an upright 6|, bolted at 62 to the plate 53, the connecting rods V5'6 and'51 extending respectively, each through an orifice trough-shaped lever, vand having a connection with the short arm 64 by means of a ball 65, (see Fig. 4) which is embraced between the cupped ends of screws 66 which are locked by nuts B1 in a position which permits easy play of the connection. The effective length of each rod 56, 51,

, may be adjusted, as by lock nuts 68 and 69.

At thefree end of each of the levers L? and L", which are symmetrically disposed relatively to each other, is a rivet and hanger connection 10, 1|, with a connector 12,Y 13, constituting terminals of a flexible member -14, preferably a chain, which is coiled upon a barrel 15 (see Fig. 3), having an axial shaft16 to which is aixed the point,- er P. Accordingly, the shaft 16 is Supported by the chain, and its ends project into slots 11 formed in upright plates 18 and 19 forming part of the head structure. l

A yoke 85 is connected with the ends ,ofthe Shaft 16. and another chain 8 l reenacted l.with

63 in the bottom of its the hook-shaped yoke 80, is lwound helically` arounda barrel 82 and its freev end is securedto a coil spring v83 (see Fig. 2)l attached at84 tothe Vframe member 85.

The barrel 82 has a shaft journaled inthe members 18, 19, and 85 of .the frame, and tothe rear end of this shaft is aflixed the.shank.8,1 of the pointer P.

In the operation of .the mechanism, if a sheathed conduit be .extended into the position of the conduit C, as shown in Fig. l2, resting on the rolls A and A", and with the free abutments M and M substantially in the positions illustrated inthat gure, the abutment .system will remainwith its fixed abutment members A and A and .itsmovable abutment members M and M in their illustrated relative positions.. If, however, as the hose is moved longitudinally through the device, the sheathing shallbe .thicker on one side of the cross section than on the other, then the rollers M' and M will Ibe either or both of them moved accordingly andthe difference on the two sides will be indicatedby the position of the pointer P" with reference to the central or neutralpositions, and the side of that position uponwhich the pointer is moved will indicate the side of the hose which is thicker.v Not only is it desired to indicate the relative thickness of the two sides of the hose, but it is desired to indicate the mean thickness at any particular i cross section of the hose, and this is occasioned by noting the average positions of .the rollers M Vand M. Such average movement may be stated in another way to be the the axis of the tube, and this pointer P on one side or the shiftingradially of is indicated by the other of its Vcentral 'or neutral position, which may be noted on .its

adjacent scale. The shifting of the tube axisin onevdirection being indicated by the position of the pointer on one side of the neutral position and the shifting ofthe axis in the other direction being noted by the position of the pointer .on the other side of the neutral position. This mean value gives an index of the body ofthe hose passing throughv the instrument While the pointer P indicates the variation sidetoside of the body.

Referring to Figs. 9 and 10, the apparatus therein shown is better adapted for portability than that heretofore referred to and comprisesv a iiat bar |03 of rectangular cross section has sliding vupon it a carriage |114 which may be secured in any adjusted position by means of a set screw |05. Fixed to one end of the bar |03 is a head |06 having recesses in which rollers |,1 and |58 are journaled on axes at angles with each other. The carriage comprises a plate vIt?! on the back of which are mounted `tvvo longitudinally slidableplungers ||0 and arranged at an angle to each other and each having a fork |2 at one end and a head i3 at the other end, rollers ||4 and ||5, with their axes at anangle, being journaled respectively intheforls of the plungers ||0 and f Having one end secured -to thehead on the plunger is a cord or band ||6 which, after 'passing` about the idler pulley ||1, vhas its other end secured to one end of the lever or whiflletree |'|8. Similarly a cord H9 has one end secured to the head of the plunger and, after passing about'the idler pulley |21),k has its other end securedto the end of the whiiiletree opposite to that at which thecord |6 issecured. At an intermediate p oint the Whilletreey or .lever .||8 .is Aipvcted the .levis f L? l Secured .to one `eind of r`the cord or band |26 on the plate |09.

" what are considered |22 which is given one or more turns about the)A rotary barrel |23 "and passes on to haveits end securedto one end of the tension spring |24, the otherA end of such spring being secured to a stationary anchorage the rtatabie pivot the .plate |09 and The barrel |23 is fixed on |26 which extends through has xed to it at the front ofthe plate the indicating pointer or needle |21'moving'over the scale' |28 on the front of the plate.

To press the carriage and bar |03 rmly together at all times, a comparatively stiff spring .|29 is fixed to an'extension plate or bar |30 .extending from the carriage and passes around and bears against the opposite'side of the flat bar |03.

In the use of the apparatus, the carriage is -slid along the bar |03 so as to permit the article to be measured, such as a rubber'sheathed hose C, to be placed in and |08 as indicated in Fig. 9. The carriage is then slid toward the hose until the rollers ||4 vand I|5 will occupy the position of a normallyshaped and normally-sized hose. The hose is then relatively moved endwise through therollv"ers either by'moving the rollers and connected apparatus with relation to the hose, or the hose With relation to the rollers, or both.

Should the diameter under the roller l I4 vary, the. plunger will slide accordingly and the cord or belt I6 will be pulled on or slackened so that the end of the Whifiletree to which the cord is connected will be either dravvn to the left or permitted to move to the right under the iniiuence of the spring |24. Similarly the increased or lessening of the diameter of the hose under the roller will cause a corresponding sliding of. theplunger and a corresponding movementof the end of the Whifetree ||8 to which the cord or belt ||9 is connected.

It Will be seen that the movement of the inv clicator |21 will be dependent upon the movement of the translation of the clevis |2| and that the movement vof this clevis is jointly dependent upon the movements of the plungers I0 and brought about by the movement of the rollers ||4 and ||5 as the diameters of the hose under fsuch rollers respectively are increased or 'del creased. The movement of the clevis therefore vrvvill be an indication of the mean variation of the hose diametersand accordingly the needle .|21 Will indicate, by its position on the scale |28, themean variation of thediameters'oi the hose, the instrument being ordinarily set so that With no variation from the normal turning the needle Will stand on zero.

While the invention has been illustrated in its best applications it may have other embodiments Without departing from its spirit and are not therefore limitedto the vstructures shown in the drawings.
